Question

the surface area of a cylinder of radius 2.0 cm and height 10.0 cm is equal to.?

Answer 1

Surface area of cylinder without base = 2 x 3.1416 x r X h = 125.664 sq. cm (approx)

If you want to add base , then add 2 x 3.1416 x r^2 i.e 25.133 to it .

So, surface area of cylinder with base = 150.8 sq cm (approx)
